Need help with slightly modified Scroll SDK example

Another option - I realize you're loading from USB/external - but you could probably get away with copying 100 of those images into the tmp storage area of the roku and then they should swap in and out of ram quicker that way one at a time. If you don't mind the initial copying delay process. Rather than scrolling the images, you could also try chopping each page into individual frames with a left/right control sequence for next and previous frame to reduce the loading and rendering time.
